ROOFING MATERIAL Filed May 27, 1944 Patented July 30, 1946 UNITED STATESPATENT OFFICE 6 Claims.

This invention relates to new and useful improvements in a roofingmaterial.

More particularly, the invention proposes the construction of a newroofing material which is superior to any roofing material heretoforemade. It is proposed to characterize the improved roofing material bythe fact that it is a flexible sheetlike material and has an internalwire mesh or perforated sheet layer.

The invention proposes a new and novel construction by which the roofingmaterial is waterproof and heat proof.

It is proposed to provide asbestos fibre layers against the faces of thewire layer. it is proposed to arrange water and heat proof sheets on theouter faces of said asbestos layers spaced from each other. It isproposed to provide an asphaltum outer covering extending over saidwater and heat proof sheets and through the portion of the asbestosfibre layers which are located adjacent edges of adjacent sheets of saidWater and heat proof sheets.

It is proposed that said asphaltum material also engage through theopenings of the wire mesh or perforated sheets in the areas indicated inthe previous paragraph.

The advantage of the new roof material resides in the fact that its heatproof and waterproof qualities are superior to similar materialsheretofore made.

Another object of the invention is the construction of a material asmentioned which is simple and durable and which may be manufactured andsold at a reasonable cost.

For further comprehension of the invention, and of the objects andadvantages thereof, reference will be had to the following descriptionand accompanying drawing, and to the appended claims in which theVarious novel features of the invention are more particularly set forth.

In the accompanying drawing forming a material part of this disclosure:

Fig. l is a perspective View of a roll of roofing material constructedin accordance with this invention.

Fig. 2 is a fragmentary enlarged elevational View of a piece of saidroofing material.

Fig. 3 is a longitudinal sectional view taken on the line 3 3 of Fig. 2.

Fig. 4 is a fragmentary perspective view of the wire mesh shown in Fig.3.

Fig. 5 is a sectional view similar to Fig. 3 but showing a piece ofroofing material constructed according to a modified form of theinvention.

Fig. 6 is a fragmentary perspective view 0f the perforated sheet shownin Fig. 5.

The roofing material, according to this invention, comprises a flexiblesheet-like strip I0 which preferably is wound into a roll, said strip I0has an internal wire mesh layer Il. Asbestos fibre layers I2 are locatedagainst the faces of the wire layer II. A plurality of spaced water andheat proof sheets I3 are disposed against the outer faces of saidasbestos fibre layers. An asphaltum covering I4 extends over said waterand heat proof sheets I3 and through the portions of said asbestos fibrelayers I2 at certain areas thereof. More particularly, the asphaltumcover I4 extends through the areas I4a which are located betweenadjacent edges of adjacent sheets I3 of said water and heat proof sheetsI3.

The wire mesh layer II comprises the usual wire mesh sheet made frominterwoven warp and weit wires. The asbestos fibre layers I2 are formedfrom asbestos material which is picked or spun into fibre-like piecesinterengaged with each other to have a plurality of air pockets t0 actas heat insulation pockets. The spaced Water and heat proof sheets I3preferably consist of waterproofed cellulose film. This film is capableof standing temperatures in excess to the melting temperature of theouter covering of the asphaltum material I4.

The water and heat proof sheets I3 protect the asbestos fibre layers I2from the asphaltum I4 so that the asphaltum does not enter and clog thepores of air pockets of the asbestos fibre layers I2, except at theareas Illa. These areas I4a are used to bind the asbestos fibre layersI2 and the wire mesh layer II together as a unit. The areas I4@ aresimilar to the tufting of a mattress in that they prevent layers fromshifting. The improved roofing material makes a good heat insulationsheet because of the entrapped air pockets in the asbestos fibre layersI2 between the water and heat proof sheets I3.

In Figs. 5 and 6 a modified form of the invention is disclosed in whichthe roofing material includes an internal fiexible perforated sheetmaterial strip 2 I. Asbestos fibre layers 22 are located against thefaces of the perforated sheet 2l. A plurality of spaced water and heatproof sheets 23 are disposed against the outer faces of said asbestosfibre layers 22. An asphaltum covering 24 extends over said water andheat proof sheets 23 and through the portions of the asbestos fibrelayers 22 at the areas 24a located between the adjacent edges ofadjacent sheets 23.

The perforated sheet 2| comprises a flexible metal sheet formed with aplurality of circular perforations or holes 25 arranged in horizontallines staggered from each other.

In other respects the functioning of this improved roofing material isidentical to the prior form.

It is to be understood that this roofing material may be secured on topof the finished tar, paper or metal roofing or side walls, by rivetingor by any other manner.

While I have illustrated and described the preferred embodiments of myinvention, it is to be understood that I do not limit myself to theprecise constructions herein disclosed and the right is reserved to allchanges and modifications coming within the scope of the invention asdefined in the appended claims.

Having thus described my invention, what I claim as new and desire tosecure by United States Letters Patent is:
